ABSTRACT:
Reactive dyes of the formula ##STR1## in which D is the radical of an organic dye of the monoazo, polyazo, metal complex azo, anthraquinone, phthalocyanine, formazan, azomethine, dioxazine, phenazine, stilbene, triphenylmethane, xanthene, thioxanthone, nitroaryl, naphthoquinone, pyrenequinone or perylenetetracarbimide series, R is hydrogen or substituted or unsubstituted C.sub.1-4 -alkyl, A is a polymethylene radical having 2 to 6 C atoms (or its branched isomers) which can be substituted by chlorine, bromine, fluorine, hydroxyl, sulfato, acyloxy having 1 to 4 C atoms, cyano, carboxyl, alkoxycarbonyl having 1 to 5 C atoms or carbamoyl, or an alkyleneoxalkylene radical having 1 to 6 C atoms in each alkylene member, independently of each other; Y is a radical --CH.dbd.CH.sub.2 or --CH.sub.2 CH.sub.2 --Z, Z is an inorganic or organic radical detachable under alkaline conditions, B is hydrogen or the radical of a substituted or unsubstituted hydrocarbon, and n is 1 or 2, are suitable for dyeing or printing cellulose-containing and nitrogen-containing materials and in a high dyeing yield produce dyeings and prints of good fastness properties.
